This example draws a pink, animated face using D3 v7, rendering SVG shapes within a circular head. It builds the eyes, eyebrows, and a mouth using `circle`, `rect`, and `path` elements, with the mouth shaped via the `d3.arc` function. The eyebrows animate vertically using `transition().duration()` to move them up and then back down. The code imports `select` and `arc` directly from the D3 module and structures the facial features through nested SVG groups with translate transforms.
